Abstract
"FLUIDO PARA PERFURAçãO à BASE DE áGUA, COMPOSIçãO PARA MISTURAR COM áGUA PARA FORMAR UM FLUIDO PARA PERFURAçãO, E, PROCESSO PARA PERFURAR UM FURO DE POçO HORIZONTAL COM UM FLUIDO PARA PERFURAçãO". é divulgada uma composição compreendendo uma argila inchável por água, particularmente uma argila montmorillonita de sódio tal como a bentonita, carbonato de sódio e um biopolímero solúvel em água, particularmente um biopolímero de xantana. A composição quando misturada com água doce forma uma lama aquosa para perfuração que possui as propriedades de fluido desejadas incluindo um elevado perfil de resistência de gel de 10 segundos/10 minutos/30 minutos e uma baixa perda API de fluido, para uso em perfurações direcionais sem abertura de vala, incluindo perfuração direcional mini-horizontal, furacão guiada, perfuração por trado, encamisamento de tubulação, microtúneis e travessia de rios. A composição misturada com um meio aquoso proporciona uma lama para perfuração à base aplicável a perfurações direcionais sem abertura de vala em uma formação de solo não consolidada e particularmente em um ambiente contaminado com água salgada tal como água do mar. A composição contém uma mistura de aproximadamente 91 a 98% em peso de bentonita Wymonig, aproximadamente 1 a 8% em peso de sal carbonato de metal alcalino, e aproximadamente 0,5 a 4% em peso de um biopolímero de xantana seletivo."WATER-BASED DRILLING FLUID, COMPOSITION TO MIX WITH WATER TO FORM A DRILLING FLUID, AND, PROCESS TO DRILL A HORIZONTAL WELL HOLE WITH A DRILLING FLUID". a composition is disclosed comprising a water-swellable clay, particularly sodium montmorillonite clay such as bentonite, sodium carbonate and a water-soluble biopolymer, particularly a xanthan biopolymer. The composition when mixed with fresh water forms an aqueous drilling mud that has the desired fluid properties including a high gel resistance profile of 10 seconds / 10 minutes / 30 minutes and a low API fluid loss, for use in directional drilling without trenching, including mini-horizontal directional drilling, guided drilling, auger drilling, pipe jacketing, microtunnels and river crossing. The composition mixed with an aqueous medium provides a base drilling mud applicable to directional drilling without trenching in an unconsolidated soil formation and particularly in an environment contaminated with salt water such as sea water. The composition contains a mixture of approximately 91 to 98% by weight of Wymonig bentonite, approximately 1 to 8% by weight of alkali metal carbonate salt, and approximately 0.5 to 4% by weight of a selective xanthan biopolymer.
